🗒️ Ingredients

For the exact measurements for the Pizza Casserole Recipe, please refer to the printable recipe card at the bottom of this post.
- spaghetti noodles - you can certainly substitute other types of pasta like egg noodles or rotini if you'd prefer.
- spaghetti sauce - use your favorite store-bought marinara sauce or use homemade.
- canned french onion soup - the canned soup keeps the noodles super saucy.
- pepperoni - load it up with lots of pepperoni slices. Browned Italian sausage would be another great addition! Substitute turkey pepperoni if you'd prefer.
- mozzarella cheese - I used pre-shredded mozzarella cheese.
- smoked provolone cheese - smoked slices if you can find it, otherwise just use regular provolone cheese. A little Parmesan Cheese would be a great addition.
- canned mushrooms, olives, bell peppers - red or green pepper, use your favorite and onions - all of these are truly optional, but I really enjoy the combination.

🙋♀️ FAQ's
Use a good jarred marinara sauce, that's perfect for this recipe! My favorite sauces are Classic Traditional, Barilla Tomato u0026 Basil. Trader Joe's has a great pasta sauce as we'll.
Absolutely this casserole freezes really well.
A combination of Italian cheese is delicious! Mozzarella cheese is best and pre-shredded cheese works well for this recipe. The smoked provolone cheese adds a decadent cheesy deliciousness as well!
Absolutely, this can be made the day ahead and baked the next day. You may need to add a little baking time if the casserole dish is cold.
You can use pizza sauce, but it's much more expensive and frankly you'll get all the flavor from a great store-bought pasta sauce. (And spend less money!)
👍 Tips
Be sure to cook the pasta to al dente. Don't over cook the pasta!
Allow the pasta to rest covered after baking for at least 10 minutes. It allows the flavors to come together. It will be easier to dish up as well.
📓 Variations
A pound of ground beef, lean ground turkey or chicken, or pork sausage would be terrific! Just make sure you cook ground meat first over medium heat in a large skillet. Drain on paper towel to remove grease before adding to the casserole.
Substitute with whole wheat or gluten free pasta if you'd prefer!
Basically any of your favorite pizza flavors that you'd NORMALLY put on a pizza would taste yummy on this easy pizza casserole! Diced bell pepper, red onions, olives, Italian sausage, etc.
Storage
Refrigerate - Allow the pizza spaghetti bake to cool completely. Store in an airtight container in the refrigerator. Leftovers will last 3-4 days refrigerator.
Freeze - Up to three months frozen.
Reheat - thaw overnight in the refrigerator. Preheat the oven to 375 degrees. Cover the casserole with aluminum foil, place in preheated oven for 30-40 minutes until the past dish is bubbly and heated through.

Serving suggestions
I can pretty much justify this as a complete meal, I mean it has plenty of veggies, right? 😋 Serve this with a green salad - like this garden salad or even a bagged caesar would be delicious!
Roasted vegetables would be great as well like Roasted Brussels sprouts or pan roasted vegetables.
This easy Dinner rolls recipe or these Copycat Pizza Hut Breadsticks would be terrific to round out this meal.
